BAGASSE-FURNACE.

Specification of Letters Patent No. 22,353, dated December 21, 1858.

To all whom it may concern:

Be it known that I, F :Lix DAUNOY, of Carrallton, parish of Jefferson, State of Louisiana, have made a new and useful Improvement in Bagasse-Furnaces; and I hereby declare the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, the same letters being used to show the same parts in the different figures.

Figure l, sectional front elevation; Fig. 2, sectional side elevation; Fig. 8, ground view below line, 00, in Fig. 1; Fig. i, inte- 7 front elevation.

I have not shown the hopper to receive the bagasse from the carrierthis being well understood how to construct, I do not deem a plan of it, on this account necessary-the position for it, mounted over the opening, 0, seen in Figs. 1 and 2. The lower section of the furnace, having the flue, the interior of it marked, F, and the crown, 0, extending through the rear wall, to the front wall;

thus dividing the base of the furnace into separate compartments for the bagasse to rest in during its combustion; as this fuel falls through the opening (0), it comes on the crown of the fine, and tumbles to either side, and rests on the grates, B, to be there consumed-the flue having exit openings, K, to allow the gas to pass in, and be conducted to the boilers out of the furnace the arrangement of the boilers not shown, this being identical with the other modes of setting, which are well understood, and as the boilers to furnish steam for sugar apparatus, being located to meet the arrangement of the sugar housethe heat to act on them, when produced from bagasse conducted by a fine made for that purpose the furnace being confined to position to suit the sugar mill. Therefore, I have omitted showing the connection of the boilers with the furnace, as any one way shown, owing to the circumstances stated, might require entirely different connection from that shown. I have a chamber on each side, for the combustion of dry fuel; namely, wood or coal the grates of which are marked, G, and the crown, A, being more particularly shown in Figs. 1 and 4, Fig. 4 made to explain this arrangement, and taken from line, Z, in Fig. 1, looking toward the center of the furnace. D, the walls of the furnace. F, the flue, K, openings in the flue. A, the crown of the wood or coal chamber, made skeleton, to allow the flame to pass through, and over, or through the bagasse, and into the flue. G, the grates. E the fuel door. J, the air door. Fig. 2, taken from line, S, in Fig. 1, showing the interior of the flue with its door, V, &c., Fig. 3, taken from line, X, in Fig. 1, showing the crown of the wood or coal furnace, marked, A, the bagasse grates (made of brick) marked, B. F, the fine. K the openings. 1), the walls of the furnaceFig. 5 only a plain front, fuel doors, E, air doors to wood furnace, J, air doors to bagasse chambers, I, and door to flue, V. In this arrangement, constructed for and intended to burn the distinct characters of fuel specified in separate compartments, and having each compartment arranged to receive its supply of air separately, so combustion can go on in each 1ndependent'of the other, and without one of the kinds of fuel absorbing the oxygen necessary to be present to aid the combustion of the other, and at the same time securing the gases produced from each mingling in their exit, also causing the gas from the wood or coal furnace to act in passing to the flue on the bagasse, and insure its immediate drying, the bagasse at the same time having oxygen free from deterioration, which must be if all the air is admitted in the one chamber; namely, that when the dry fuel is consumedwill insure its rapid combustion-and should the wood or coal (owing to the bagasse producing ample heat) be dispensed with-and the accumulation of the bagasse cause it to rest on the crown of the dry fuel chamberthe mode of construction of this crown, becomes at once the grates for the bagasse. The air necessary to cause the combustion in this position, can be admitted through the doors, E, thus having the upper strata of bagasse supplied with fresh air, without counteracting the supply through the grates, B. I wish it distinctly understood, the bagasse is consumed above, B, or, A, no intention for this fuel to be consumed below either.

After this my description, what I claim a skeleton crown, and the grates, B, on as new and desire to secure by Letters Pat which the bagasse is consumed; When made 10 ent, is and arranged substantially as, and for the The construction of bagasse furnaces, havpurpose set forth. 5 ing the exit flue F located in the interior of FELIX DAUNOY.
